境を提供する。Referring to FIG. 5, the operation when the present invention is used as a food drying apparatus will be described. After the door on the front of the drying device is opened and the net shelf 5 is pulled out, the objects to be heated 4 are placed on the net shelf 5 and the objects to be heated 4 are stored one by one. After the setting of all the objects to be heated 4 is completed, the door is closed. The drying mode can be selected from an oxygen-free atmosphere drying or inert odor countermeasure mode using an inert gas and a normal suction / exhaust drying mode. Select according to conditions. For example, in the dry odor control mode, the intake blower 26 and the air damper 27 are closed, and the dehumidifying heat exchanger 25 operates. In the case of the normal drying mode, the suction blower 26 and the air damper 27 operate, and the dehumidifying heat exchanger 25 is operated.
Is optional. As for the heat transport liquid 1, a sufficiently degassed hot water or edible oil from which moisture has been removed is supplied to a liquid heater 2.

Thus, the heat is supplied to the heat dissipation panel 3 from the inflow header 19 of the heat dissipation panel 3. The heat radiating panel 3 is heated by the heat transport liquid 1 and emits heat radiation 10 and convective heat 11 corresponding to the temperature of the heat radiating panel 3. The heat transport liquid 1 that has supplied heat to the heating panel 3 is collected in the outflow header -20, returns to the liquid heater 21, and is used repeatedly. The circulating air 9 in the drying chamber is sent to the heating / drying unit and the dehumidifying heat exchanger 25 by the circulating fan 24 of the main fan. In particular, the ventilation of the heating / drying unit is appropriately controlled by the exhaust fan 6 and the ventilation guide vanes 7 arranged between the heat radiation panels 3. The temperature and humidity of the circulating air 9 or the inert gas in the drying chamber are detected by temperature / humidity sensors -28 and 29, and the temperature in the liquid heater is detected by the temperature sensor-30 and transmitted to the control unit 31.
The control unit 31 controls the liquid heater 21, the circulation pump 22, and the circulation blower 2 based on the data of the drying operation input in advance.
4. The exhaust fan 6, the dehumidifying heat exchanger 25, the intake blower 26, and the air damper 27 are controlled to provide a drying environment suitable for the object 4 to be heated.

乾燥が可能となった。In the food drying apparatus according to the present invention, hot water or edible oil is used as the heat transport liquid. Hot water or edible oil is safe, inexpensive, and easy to handle and replenish. In particular, in a device that handles food, disassembly and cleaning of the device must be performed safely and easily on a daily basis from the viewpoint of food hygiene. The heat transport liquid was selected in consideration of these.
In the heating drying process, to prevent heat denaturation and discoloration due to heating, and to achieve high quality and high efficiency drying, means to make the heat exchange between the radiating panel and the heated object effective, for example,
Fins were attached to the heat dissipating panels, and appropriate ventilation was supplied between the net shelves to enable heating and drying at a relatively low temperature. In the air circulation, a dehumidifying heat exchanger was incorporated for the purpose of drying in an inert gas atmosphere and measures against dry odors, enabling multipurpose drying and improving handling. From the above, high-quality and highly-efficient drying of foods, especially chilimen and dried sardines, has become possible.
